Can't create XMLType based on OPAQUE in Java+JDBC

Question

Hi,
I'm querying the database using Java and JDBC. The resulting column (there is only one) is of type SYS.XMLTYPE. When I want to create an object of class XMLType of the data in this column I'm getting an error in the orageneric.dll.
The (partial) code I use is:
        OracleResultSetMetaData metaData = (OracleResultSetMetaData)rs.getMetaData();
        int columnCount = metaData.getColumnCount();
        if((columnCount==1) && (metaData.getColumnTypeName(1).equals("SYS.XMLTYPE"))) {
            System.out.println(metaData.getColumnClassName(1));
            XMLType xt = XMLType.createXML(rs.getOPAQUE(1));This is based on some example code in:
http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28369/xdb11jav.htm
When I run this I'm getting the following error:
java.lang.UnsatisfiedLinkError: C:\app\tijink\product\11.1.0\client_2\BIN\orageneric11.dll: The specified procedure could not be found
        at java.lang.ClassLoader$NativeLibrary.load(Native Method)

        at oracle.xdb.XMLType.initConn(XMLType.java:3267)
        at oracle.xdb.XMLType.<init>(XMLType.java:1225)
        at oracle.xdb.XMLType.createXML(XMLType.java:698)I've tried a different version of getting the XMLType object:
            XMLType xml2 = (XMLType)rs.getObject(1);This is based on the example in the XMLDB forum FAQ (How do I access XMLType using JDBC ?
This gives the following casting error:
java.lang.ClassCastException: oracle.sql.OPAQUE cannot be cast to oracle.xdb.XMLTypeI'm a bit lost... any suggestion would be helpful

Answer 1

Harald, also post this question on the java/xdk forum.
A long time ago (2 / 3 years) while fiddling around with XSQL (from the XDK), trying to create XML webpages, I run into several OPAQUE issues as well and I was able to solve them via a lot of info on the java forum (but maybe a java enthousiast here can solve it / answer it anyway). Just a suggestion.
